Stack0 gives you a complete backend through a single SDK. Install the package, add your API key, and you can send emails, store files, process video, take screenshots, extract data, and connect to third-party services — all from one import.
No more stitching together Resend for email, S3 for files, Mux for video, and building your own integrations. Stack0 replaces all of them with one consistent, type-safe API. Every service works the same way: initialize, call, done.
It works with any framework — Next.js, Express, Hono, FastAPI, Rails, and more. SDKs for TypeScript, Python, Ruby, and Go. AI agents can use it as a tool to interact with the real world. You pay only for what you use, starting at $5/month.
